Experiment on pre-emergence and post-emergence herbicide application for weed control in farmer's field conducted in Ban Yangrak, Khokcharoen district, Lopburi province, during August-November 2008. The experiment laid out in RCB, composed of 10 treatments, with 3 replications. The objective of this experiment was to study on the efficiency of herbicides and their effect on field corn, KSX 4901 variety. The results revealed that weed found in the experiment were purple nutsedge (Cyperus rotundus), wild poinsettia (Euphorbia heterophylla), horse purslane (Portulaca oleracea), tropical spiderwort (Commelina benghalensis), running grass (Brachiaria reptans), and jungle rice (Echinichloa colona). The application of 2,4-D, glufosinate, fluroxypyr and paraquat as post-emergence herbicide gave better weed control than atrazine, the pre-emergence herbicide. Application of 2,4-D+paraguat gave as good weed control of 80 percent, as hand weeding of 87 percent. All herbicide treatments were not affect to corn yield, seed moisture content, shelling percentage, plant height and ear height. Yield of KSX 4901 from the experiment were 602-745 kg/rai.
